"I'm angry and something has to be done," said Claudia Towns, the victim's mother.

Channel 2 investigative reporter Mark Winne, who has broken nearly every major development in this case, has learned a sergeant resigned. A lawyer representing another officer says his client continues to fight his proposed firing.

The lawyer said of the suit, "At least the process of revealing the truth can begin," and that his client said Gregory Towns never complained of medical issues during the incident.
